DUAL PURPOSE CREEL ADAPTER Filed Aug. 26, 1947 INVENTOR. 6AMUEL ems QOU6HEWTY Patented Aug. 14, 1951 UNITED STATES PATENT OFFICE DUAL PURPOSE CREEL ADAPTER Samuel Ross Dougherty, Ridley Park, Pa., assignor to American Viscose Corporation, Wilmington, Del., a corporation of Delaware Application August26, 1947, Serial No. 770,727 I 4 Claims. (Cl. 242130) This invention relates to package supporting means. More particularly this invention relates to supporting means for packages of filamentary material that is wound on either bobbins or cones.

In various textile operations it is necessary to firmly support packages of filamentary material while the filamentary material isbeing wound on 'is also desirable that the package be readily mountable on the supporting means and also readily removable therefrom.

This invention has for its principal object to provide a simplified form of unitary filamentary package supporting means that securely supports the package and on which the package may be quickly mounted and from which the package may be readily removed.

Another object of this invention is to provide a simplified form of unitary filamentary package supporting means that is applicable to packages of filamentary material that is wound on bobbins or cones of various sizes.

A further object of this invention is to provide a simplified form of unitary filamentary package supporting means thatis applicable for use with either stationary or rotating packages.

Otherobjects and advantages of the invention will be apparent from the following description and the accompanying drawings.

Figure 5 is an elevational view in section or a further embodiment of the invention.

This invention in general comprises a package supporting spindle having on the spindle or adiacent the spindle an elastic deformable member with means for deforming the member ina direction to cause the member to either engage or retract from engagement with the inner wall of a bobbin or cone on which filamentary material is wound or is to be wound.

Referring to Figures 1 and 2 of the drawing. ref erence character I indicates a stationary supporting means in whichis fixed a stationary bushing or hollow member I. A stem-like member 3 is slidably mounted in the bushing and a spindle 4 of greater diameter than the stem-like member, spaced from the bushing, is fixed to or made integral with the stem-like member. An annular sleeve-like member 5 of elastic readily deformable material, such as rubber or the like, is freely mounted on the stem-like member and positioned between the bushing and the spindle. A pair of disk-like members 6 are pivotally and eccentrically mounted on the end of the stem-like The disk-like members are fixed together and may be rotated on the pin by means of the handle 8. The distance of the pin member from the end of the bushing and the size and eccentricity of the disklike membersare such that the disk-like members may be rotated into engagement with the bushing to move the stem-like member longitudinally through the bushing to the left as shown in Figure 1. The sleeve-like member when not deformed is of the same diameter as that of the spindle. v

. In the operation of this form of device the disklike members are rotated out oi engagement with the bushingand .a packageof filamentary I stem member to move axially through the bushing toward the left. During this movement the spindle l presses against the end of the sleeve-like member 5 compressing the membervina longitudinal direction and causing it to expandain a radial direction to firmly engage-the bobbin or cone or the package of filamentary material positioned thereon throughout its length yln this position the sleeve-likemember yieldably but firmly engages the bore of the bobbin orfcone on which the filamentary material is wound and securely retains the package on the spindle- To release the package-from the supporting means, thefdi'sk members as shown in Figure 1 of the drawingl jare rotated in a clockwise direction out 01- engagement with the bushing permitting the sleeve-like member to expand in a longitudinal direction and contract in a radial direction out of engagement with the bobbin or cone. The package may then be easily slipped off the spindle.

Referring to Figures 3 and 4 of the drawing in which another embodiment of the invention is shown, reference character la indicates a stationary supporting means in which is fixed the bushing 2a. A stem-like member 3a. is slidably mounted in the bushing and the spindle la of larger diameter than the stem-like member spaced from the bushing is fixed to or made integral with the stem-like member. An annular sleeve-like member 5a of elastic readily deformable material such as rubber or the like is mounted on the stemlike member and positioned between the bushing and the spindle. The sleeve-like member is fixed at one end to the bushing and at the other end to the spindle by cement, clamping means or the like. A disk-like member 6a is pivotally mounted in the end of the bushing in a slot formed therein by means of the pin la and is adapted to be rotated on the pin by means of the handle 8a. The length of the stem-like member and the size and eccentricity of the disk are such that the disk may be rotated into engagement with the end of the stem-like member that extends into the bushing to move the stem-like member longitudinally. The sleeve-like member when in relaxed condition or not deformed is of slightly greater diameter than the spindle. In the operation of this embodiment of the invention the disklike member is rotated in a counter-clockwise direction into engagement with the stem-like member to move the stem-like member to the right as shown in Figure 3 of the drawing which elongates the sleeve-like member and reduces its diameter to that of the spindle. A package of filamentary material wound on a hollow bobbin or a cone indicated generally by reference character 9a is passed over the spindle and sleevelike member into engagement with the stationary support shown by reference character la. The disk-like member as shown in Figure 3 of the drawing is then rotated in a clockwise direction out of engagement with the stem-like member permitting the sleeve-like member to contract longitudinally and expand radially outwardly into firm engagement with the inner wall of the bore of the bobbin or cone on which the filamentary material is wound. The sleeve-like,

the stem-like member and to move the stem-like member longitudinally in the bushing to the right to elongate the sleeve-like member and contract the sleeve-like member in a radial direction out of engagement with the inner wall or bore of the cone or bobbin. Then the package of filamentary material may be slipped off the spindle.

The further embodiment of the invention shown in Figure 5 of the drawing is applicable to a rotating support for a bobbin or cone on which filamentary material is being wound. As shown in this figure of the drawing reference character l0 indicates a stationary support on which the spindle l I is rotatably mounted in the bearing 12. Means not shown are provided for rotating the spindle. An annular member [3 is fixed to the spindle adjacent its free end by means of a set screw it. An annular flange-like member 22 is collar member I5 is rotatably and slidably mounted on the spindle and is provided with an annular extension 11. The extension is provided with longitudinally extending slots 24 through which the pin member 23 extends. An annular sleeve-like member is of elastic readily deformable material such as rubber or the like is mounted on the spindle and positioned between the annular member 13 and the collar extension H. The sleeve-like member is fixed at one end to the annular member l3 and at the other end to the collar extension by adhesive or other securing means. The collar member is adapted to be moved longitudinally of the spindle by means of the disk 2| that is eccentrically and pivotally mounted on the bracket 26 by means of the pin 2!). Handle means l9 are provided for rotatin the disk-like member. The sleeve-like member l8 when in relaxed condition is of greater diameter than the annular member ill or the collar extension H.

In the operation of the further embodiment of the invention shown in Figure 5'the disk-like member is rotated into engagement with the collar member to move the collar member to the left on the spindle II. This action causes the sleeve-like member l8 to be elongated and to reduce the diameter to the diameter of the annular member l3 and the collar extension I]. A tube 25 on which filamentary material is to be wound is passed over the sleeve-like member. The disk 2| is then rotated out of engagement with the collar member permitting the sleeve-like member to contract longitudinally and expand in diameter to yieldably but firmly engage the inner wall of the tube.

While preferred embodiments of the invention have been shown it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
